A man comes across three old men outside a pub

I remember one says -
Alcohol has never passed me lips nor smoke into me lungs
it's my recipe for long life and a way of staying young


And the third claims that he has drunk smokes and chased women all his life

Then the man says

Tell me just how long sir have you lived in this way

he replies with the punch line

I've lived man and boy sir 23 years to the day.
